// that public state surface; the geometry derivation itself (toolbar/footer/menu rects,
// row/cluster builders, region rects, the L7 slot-order display bridge) is internal to

// REAPER-free: main.cpp / bank_actions.cpp drive these through plain free functions.

// project state, so it must not travel with the .rpp. In-memory for the extension's
